The synthesis of novel amphiphilic 5,5',6,6'-tetrachloro-benzimidacarbocyanine (TBC) dye derivatives with amino-propanediol head groups is reported, which only differ in stereochemistry (chiral enantiomers, meso-form, and conformer). For the achiral meso-form, a new synthetic route towards asymmetric cyanine dyes was established. All compounds form J-aggregates in water whose optical properties were characterized by spectroscopic methods. The supramolecular structure of the aggregates was investigated by cryo-transmissi
